RUBBER-STAMP PAD;

Application filed February 19, 1,926. Serial No. 89,468.

This invention relates to a stamp pad for use in oilices and the like.

The principal objects of the invention are to provide a construction inwhich practically all of the device that can come into Contact with thedesk is of soft material such as rubber and has a narrow soft upper edgethat will not injure the stamps; to provide means integral therewith forholding a sponge rubber pad in a rubber box under all the conditions itmay encounter during packing and shipment and' yet render it capable ofbeing removed and reversed; and to provide the rubber container withimproved means for pivotally supporting the metallic cover in such a Waythat the cover will lie fiat on the table or desk when open.

Reference is to be had to the accompanyin drawings, in which g. lis aplan of a stamp pad constructed in accordance with this invention withthe cover broken away and part of the pad also;

Fig. 2 is a transverse sectional view on the line 2-2 of Fig. l; andv vFig. 3 is an end view showing the cover open.

The pad is formed with a casing or box vl0 molded of a single piece ofsoft rubber. This has a bottom 11 and upstanding side and end walls 12between which walls is located a pad 13 nearly iiush with its uppersurface. These walls are soft enough to avoid injury to the stamp if itis brought down on the edge of the box, and yet it does not project overthe ink pad at any point.

The ink pad consists of a single piece of Hat sponge rubber with itsfour ed e and top surfaces formed by cuttin it rom a body of thatmaterial. The wa s of the box and the ad have vertical surfacescontacting with eac other and the Walls of the box have integrallymolded inwardly extending spurs 14, adapted to project into the cutedges of the pad. Thus the ink pad is held accurately in position by thespurs and-will lie at on the floor of the casing. It is held in positionby frictional contact with the walls of the casing and especially by thespursso that if inverted in packing or shipment, or otherwisemishandled, the pad will not come out, but it can be removed forinspection, repairs and replacement. It can be taken out and reversedalso if one side gets worn or filled with dust. It has great durabilityfor this reason and especially on account of the material used. Thisconstruction obviously facilitates assembling the parts.

The rubber casing l0 is provided with an integral molded fiat ledge l5extending outwardly from it all around three sides. These ledges are inthe same plane and located at the extreme bot-tom ofthe casing.

For the purpose of covering the pad I employ a sheet metal cover 20.This is provided With three :flanges 2l around the front and the twoends, and the end flanges are perforated at the rear to provide a holefor removable pivot pins or screws 22. These pivot pins extend throughthese flanges and centrally into the rubber of the rounded rear wall 12of the casing. This wall extends throughout the length of the casing. Inthis way the cover is conveniently and simply pivoted without anyspecial fastening or holding means, and it can be turned back to the:fiat position shown in Fig. 3, as there is nothing to come into contactwith the outside of the rear wall 12 to hold it up. The pins or screws22 can be removed easily by the user and the cover entirely dispensedwith thereafter. This saves desk room. The three .flanges 21 rest on theled es l5 when closed, thus keeping the cover in orizontal position andfurnishing a yielding noiseless rest for them.

This furnishes an all-rubber construction for the pad and casing, theonly metal being the cover. Therefore, it can be moved around on a deskor table at will without marring or scratching it. The rubber bottomalso prevents the accidental sliding of the pad on a desk. It holds thepad itself ,permanently so that it will not come out accidentally andstill the pad can be removed as stated above. The rubber walls l2, beingsoft, will not injure the rubber stamp if it is brought down on theirupper edges. It furnishes a very eiicient and neat construction andinvolves comparatively little expense in the manufacture.

Although I have illustrated and described only a single form of theinvention I am aware of the fact that modifications can be made thereinby any person skilled in the art without departing from the scope of theinvention as expressed in the claims. Therelfront, rear and end wal foreI do not wish to be limited to all the details of construction hereinshown or described but what I do claim is 1. As an article ofmanufacture, a stamp pad comprising a soft rubber casing in a singlepiece having upwardly extending s provided vwith a recess between themin which is located an ink pad of s onge rubber, the casing having aninte ral at soft rubber flange extending outwardly from it around it atthe extreme bottom a metal cover ivoted to the rear side of sai casingand aving three vertical flanges extendlng down therefrom adapted tocome into contact with the projecting rubber anges on said base tosupport the cover in horizontal posit-ion and having a short projectingedge along the rear, the pivots for the cover being located at oppositeends of the pad and near the extreme rear thereof, and the base beingrounded over at the rear all the way across it so that when the cover isswung back the rear edge ofthe back of the cover will avoid the rearrubber wall of the casing all the way across and hold the the cover isswung back the rear edge of the back of the cover will avoid the rearrubber wall of the casing and hold the cover in open position in theplane of the casing.

In testimony whereof I have hereunto afiixed my signature.

CARL C. HARRIS.
